I believe that the Tilt-A-Whirl was moved from Geauga Lake to replace the Rock-O-Plane and given the same name (Barracuda). A couple children's rides were also moved including the turtle ride.
I've heard so many different rumors about SFO/GL moving rides to Wyandot - everything from the boomerang, to the log flume, to Mr. Hyde's, to Raging Wolf Bobs.
